IMPROVED MODE OF OPERATING OIL-WELLS.

Specification forming part of Letters Patent NO. 50,902, dated November14, 1865.

To all whom it may concern:

Be it known that I, PAUL CAsAMAJoR, of the city, county, and State ofNew York,have invented a new and Improved Mode ot' Operating OilVells;and l do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable those skilled in the art to makeand use the same, reference being had to the accompanying drawings,forming part ot' this specitcation, in which- Figure 1 represents avertical central section ot' this invention. Fig. 2 is a horizontalsection ot' the same, the plane ot' section being indicated by the linex x, Fig. 1.

Similar letters ot' reference indicate corresponding parts.

The usual method ot1 operating oil-wells is to sink awell ot' a diameterot' four inches, (more or less,) and after tubing the same to raise theoil bysuitable pumps. By this method only that oil is reached which isincloscd in crevices that are'pierced by the well, and in order to reachall the oil in a certain tract ot' land it is necessary to sink a largenumber otA wells.

This invention consists in extending from a central vertical main well aseries ot' radiating' drills in a horizontal or inclined position insuch a manner that a communication is et'- i'ected between the severalcrevices situated outside the main well and not otherwise incommunication therewith, and all the oil contained in a certain tractot" land can be collected in thc main well and raised by one and thesame pump without the necessity ot' sinking a large number ot' wells andremoving the pump from one well to the other.

A represents a well, which, howeveigis made of a much larger diameterthan that generally given to oil-wells, and which will have to be dugout. or otherwise produced by suitable machinery. The upper portion ot'thiswell, which is supposed to pass through slate-rock, is protected byplanks a, to prevent the ground from tumbling in, and its lower portionis lined with a crib, I), of cast-iron or other suitable material, whichmay be provided with suitubleribs to keep it properly in the centerot'the well, or which maybe steadied by othersuitable means. The wellextends through the said rock containing the oil,and in order to reachsuch crevices which are not struck bythe well l erecta platt'ornnc, atasuitable height above the bottom ot' the well to enable the men to standon, and then I extend a series of radiating drills, d, in a horizontalor inclined direction from the well A,as shown in Fig-.2 ot' thedrawings. These radiating drills may he continued to any desireddistance trom the main well, and by the same a communication is openedbetween distant crevices and the well, and the oil contained in anextensive tract ot' land can be collected in one and the same well.

Suitable galleries may be d ug in the side ot' the main well to protectthe workmen in drilling the radiating` holes, and the operation ofdrilling these holes may be etected by hand or by suitable machinery.

A pump placed in the main well serves to raise the oil in the ordinarymanner.

l claim as new and desire to secure by Letters Patent- Thewithin-described method ot' operating oil-wells by extending from themain well A a series of radialingdrillsorchannels, d, in a horizontal orinclined direction, substantially as and for the purposes set t'orth.
